FREDERICK J'. RUMPELTIN, OF RIDGEWOOD, NEW JERSEY.

To all whom t may concern:

Be it known that I, FREDERICK J. RUM- .PELT1N, a citizen of the United States, residthe bowl and which will also operate to remove the incrustation or deposit which accumulates on the inner face of the wall of the bowl. l

' Further objects of the invention -willap-` pear more clearly hereinafter.

The invention consists in the general combination of parts and simplicity of details hereinatfer described. all of which contrib ute to produce an eliicient pipe cleaner. i,

A preferred embodiment of my invention-V will be-particularlydescribed ijn the following specification. while the broad scope of my invention will be pointed out in the appended claims. Y v

In the drawings. Figure 1 is a front elevation of the device indicating `the manner in which it is employed in cleaning out the cup of a pipe bowl; Fig. Qisa view similar to Fig. 1 but showing the device as in the act ot cleaning the side walls of the pipe bowl; Fig. 3 is a side elevation showing the lower part of the device, the upper part being breken away; Fig. 4 is a cross section through the device taken on the line 4 4 of Fig. l; Fig. 5 is a cross section through the device taken on the line 5 5 of Fig. 2; and Fig. 6 is a cross section through the handle of the device taken on the line 6--6 of Fig. 2. Y

Referring more particularlyto the parts, I pre-fer to construct the cleaner in two parts 7 and 8, giving the device a tube-like form, that is each of the parts 7 and S has substantially the form of one-half of a tube which is split longitudinally. The lower extremity of each part 7 and 8 is formed into a tapered semi-conical jaw 9, and these jaws have flanges or lips 10 which are normally held together in the position indicated in Fig. 1. They are preferably held in this position by means of a spring 11, which may be in the form of a coil spring held in place by pivot pin l2 which pivotally connects the Specification of Letters Patent.

two parts together. The jaws 9 when together form a substantially conical eXtension or shell which is adapted to be received in a pipe bowl 13. The lower extremity of the flanges or lips 10 form a rounded nose 14: which may be held against the cup 15 of the pipe bowl and rotates so as to clean the bowl at this point and dislodge any incrustation. The upper portion of the parts 47 and 8 form a handle 16 for the device,

consisting of two semi-tubular parts or handle extensions 16' and 16b disposed on the side of the pivot remote frcm the jaws. When these parts are forced together they overcome the force of the spring 1l and spread the jaws 9 apart. The sides of the jaws-9 are provided with Scrapers 17 which are preferably formed by forcing the material of the jaw outwardly in such a way as to forman outwardly projecting fin, and these fins preferably taper, that is they increase in width in an upward direction, so

thatwhen the jaws are opened as indicated in Fig. 2, the edges ot' these scrapers lie sub stantiallyparallel with each other and with the inner wall of the bowl of the pipe. With the cleaner held in this position it will be evident that if it is revolved the Scrapers 17 will break ofi the crust` and clean the wall ot' the bowl. lVhen the scrapers are struck from the jaws 9 as indicated, they produce elongated triangular openings 18 in the wall of each jaw.

In Fig. 4 the jaws are represented closed together, that is with their lips 10 held together as they are normally held by the spring 1l. In Fig. 5 the jaws are represented as held apart.

A pipe cleaner embodying my invention evidently may be economically formed and it will evidently operate very effectively to clean the bowl of a smokers pipe.

It is understood that the embodiment ot the invention described above is only one of the many embodiments or forms the invention may take, and I do not wish to be limited in the practice of my invention or in my claims to the particular embodiment set forth.

What I claim is:

1; A pipe cleaner consisting of two members having a pivotal connection upon each other, said members having jaws forming parts of a substantially conical shell adapted to be received within the pipe bowl, said conical shell having an integral flange pro- Vjecting outwardly at the extremity thereof i Vadapted to engage the bottom of the bowl when said jaws are closed together', said jaws having scrapers struck integrally from the conical walls thereof projecting outwardlv and extending longitudinally along the conical faces thereof, said Scrapers operating to engage the inner face of the pipe bowl when said `jaws are held separated, said members having handles adapted to be grasped to move said jaws with relation to each other.

2. A pipe cleaner consisting of two members having a pivotal connection upi-n each other, said members having jaws forming parts of a conical shell to be receivel .vithin the pipe bowl, said shell having an integral projecting flange at the extremity thereof to engage the bottom of the bowl when said jaws are closed together, saidjaws having scrapers in the form of fins struck integrally outwardly from the walls thereof project-ing -and extending longitudinally along the conical faces thereof, said Scrapers operating to engage the inner face of the pipe bowl when said jaws are held separated, said members having handles adapted to be grasped to move said jaws with relation to each other, and a spring tending to hold said jaws in an extreme position.

3. A pipe cleaner consisting of two substantially semi-tubular members oppositelyY disposed to form a handle, said members' being pivotally connected together and hav ing jaws below the pivotal connection therebetween forming a taperedV extension adapted to bereceived in a pipe, bowl, said jaws i having longitudinally disposed Scrapers struck from the materialV thereof adapted to engage the wall ofthe pipe bowl to clean the same when'sa'id cleaner' is rotated.

4. A-pipe cleaner consisting of two members having a pivotal connection upon Veach other,l said members having oppositelv disposed extensions forming a handle and having'oppositelyi disposed conical jaws, said jaws having integral flanges at the meeting edges thereof forming a rounded scraper at thel ends of said jaws for scrapingthe bottomV of the bowl of the pipe, said jaws havjf ing integral laterally projecting Scrapers in the form of tins disposed on'opposite sides of the, pivotal connection and operating to swing outwardly when said handles areV pressed to engage the inner face of the wall ot the pipe bowl, andl means tending tohold said jaws close together. Y

5. A pipe cleaner consisting substantially of two jaws, each jaw consisting of a semi# Y conical shell. said jaws having integral outwardly projecting flanges `meeting flatly together when saidV jaws are closed, a pivot connecting said jaws, said jaws having handle extensions integral therewith on the side of said pivot remote from said jaws', said jaws having'integral scrapers in the form of `tins struck -outwardly and extending longitudinally of the said jaws, and a spring engaging lsaid handle extensions normally H l holding'said jaws togethen j l i;
